No you are slowing barking up the right tree :-)

The call is getting accepted by Asterisk in the context
inbound-from-siemens. However it can't work out what to do with the
call. You need to match the xxxxxx number with a extension number which
is in the inbound-from-siemens context or another context included in
it. For instance if the xxxxxxx number is 123456 you could use.

[inbound-from-siemens]

exten => 123456,1,Dial(SIP/101)

to dial SIP phone 101

or if the numbers from the siemens follow a pattern ie they all start
with 12 then you could use

exten => _12XXXX,1,Dial(SIP/101)


If you check the extensions.conf page at

www.voip-info.org/wiki

you will see loads of examples on how to construct a dialplan
